In this episode, I’m joined by Christopher Gardner and Ty Beal to break down the science and debate behind the latest U.S. Dietary Guidelines. We explore ultra-processed foods, protein recommendations, plant-based alternatives, and how nutrition evidence is interpreted when shaping national dietary advice.
Despite disagreements on specific points, this conversation highlights how much common ground exists when scientists engage in open, constructive dialogue.
What We Cover
When you zoom out from the debates, the fundamentals remain clear: diets built around whole foods, fibre-rich plants, and minimally processed ingredients consistently support better health.
To connect with the guests and explore more of their work, follow Christopher Gardner on Instagram and LinkedIn, and learn more about his research through the Stanford Nutrition Studies Research Group. You can follow Ty Beal on Instagram, subscribe to his YouTube channel, and explore his research at tybeal.com.
